Though they were undeniably janky, I had a lot of fun doing the physics puzzles. I had to restart quite a few times, but I beat it. The core mechanics are really fun, the physics just need a lot of polish.
The placement of boxes being tied one-to-one to the distance of the cursor to the player was inconvenient at times, especially when trying to place boxes near the end of the screen. The player gains super-stretch arms when trying to place boxes to the left from the right side or the right from the left side, but has trouble the other way around.
Great job!
